Physicists have Created a Magnetic Wormhole in Lab

Physicists have created a wormhole that channels a
magnetic field through space. Study co-author Jordi Prat-Camps, who is also a
doctoral candidate in physics at the Autonomous University of Barcelona in
Spain, said "This device can transmit the magnetic field from one point in
space to another point, through a path that is magnetically invisible. From a
magnetic point of view, this device acts like a wormhole, as if the magnetic
field was transferred through an extra special dimension." The notion of a wormhole was originated from
Albert Einstein's theories. In 1935, Einstein and his partner Nathan Rosen comprehended
that the general theory of relativity permitted the presence of bridges that
could link two dissimilar points in space-time.

Hypothetically these Wormholes, also known as Einstein-Rosen
bridges, could permit something to tunnel rapidly between great distances (however
the tunnels in this concept are very tiny, so normally wouldn't fit a space
traveler). Up to now, no one has found proof that space-time wormholes really occur.
This new wormhole isn't a space-time
wormhole as such, but is instead an understanding of an innovative
"invisibility cloak" first suggested in 2007 in the journal Physical Review Letters. This kind of wormhole would hide electromagnetic waves from sight
from the outside. The actual difficulty was, to make the technique work for
light required materials that are very impractical and tough to work with, Prat
said.

Magnetic
wormhole

As research continued, scientists discovered that the
materials to create a magnetic wormhole already exist and are much easier to acquire.
Especially, superconductors, which can transmit high levels of current, or
charged particles, eject magnetic field lines from their centers, basically
bending or twisting these lines. This fundamentally permits the magnetic field
to do something different from its adjacent 3D environment, which is the first
step in hiding the disruption in a magnetic field.

So the group of scientists designed a three-layer object, comprising
of two concentric spheres with an inner spiral-cylinder. The inner layer basically
transferred a magnetic field from one end to the other, while the other two covers
acted to hide the field's presence.

Generally, magnetic field lines discharge from a definite place
and decay over time, but the existence of the magnetic field should be noticeable
from points all around it. But, the new magnetic wormhole hides the magnetic
field and funnels it from one side of the tube to another without being
detected, seeming to pop out of nowhere on the other side of the cylinder, reported
the scientists on Aug. 20 in the journal Scientific Reports.

Prat told Live Science "From a magnetic point of view,
you have the magnetic field from the magnet disappearing at one end of the
wormhole and appearing again at the other end of the wormhole,"

So What Are It’s Applications

There’s currently no way to recognize if similar magnetic
wormholes prowl in space, but this technology could have uses on Earth, Prat
said. For example, Magnetic Resonance Imaging (MRI) machines use a huge magnet
and oblige people to be in a strongly bounded central tube for diagnostic
imaging.

But if a device could transmit a magnetic field from one point
to the other, it would be probable to take images of the body with the heavy-duty
magnet located far away, freeing people from the enclosed location of an MRI
machine, Prat said.

Prat said "If you want to apply this to medical
techniques or medical equipment, for sure you will be interested in directing
toward any given direction. A spherical shape is not the most practical
geometry."
